2023 Ender 3 Power Supply Fan Silencer 9.6mm Screws

thingiverse

Summary This is a remix of @rohanisousbois remix of @Mr_Clever_Coyote fan silencer INSTALLATION: - Take off only one screw from the power supply fan and use it to screw the printed part in place - Pivot the printed part to reach the second screw - Take the second screw off and screw it back with the printed part. - This way the fan is always hold by at least one screw and won't fall into the power supply case. IMPORTANT : In 2019, the Ender 3 started shipping with 9.64mm ATX fan screws rather than 11.77mm which was the standard. This remix changes the diameter of the screw hole to 4.5mm and countersinks the screw by an additional margin to properly allow for the 9.64mm screws to work. The original design was made for redirecting airflow but had the benefit of silencing the fan as well. I took this a step further and added additional baffles for muffling the sound. I recommend using fuzzy walls as well.
